2015-05-26diff.c: --ws-error-highlight=<kind> optionLibravatar Junio C Hamano1-0/+10
Traditionally, we only cared about whitespace breakages introduced in new lines. Some people want to paint whitespace breakages on old lines, too. When they see a whitespace breakage on a new line, they can spot the same kind of whitespace breakage on the corresponding old line and want to say "Ah, those breakages are there but they were inherited from the original, so let's not touch them for now." Introduce `--ws-error-highlight=<kind>` option, that lets them pass a comma separated list of `old`, `new`, and `context` to specify what lines to highlight whitespace errors on.

2015-05-18Documentation/log: clarify what --raw meansLibravatar Matthieu Moy1-1/+10
There are several "raw formats", and describing --raw as "Generate the raw format" in the documentation for git-log seems to imply that it generates the raw *log* format. Clarify the wording by saying "raw diff format" explicitly, and make a special-case for "git log": "git log --raw" does not just change the format, it shows something which is not shown by default.

2015-05-14doc: convert AsciiDoc {?foo} to ifdef::foo[]Libravatar Jeff King1-2/+6
The former seems to just be syntactic sugar for the latter. And as it's sugar that AsciiDoctor doesn't understand, it would be nice to avoid it. Since there are only two spots, and the resulting source is not significantly harder to read, it's worth doing. Note that this does slightly affect the generated HTML (it has an extra newline), but the rendered result for both HTML and docbook should be the same (since the newline is not syntactically significant there).

Technically, "-s, --no-patch" is implemented in diff.c ("git diff --no-patch" is essentially useless, but valid). From the user point of view, this allows the documentation to show up in "git show --help", which is one of the most useful use of the option. While we're there, add a sentence explaining why the option can be useful.

2013-06-30Merge branch 'ap/diff-ignore-blank-lines'Libravatar Junio C Hamano1-0/+3
"git diff" learned a mode that ignores hunks whose change consists only of additions and removals of blank lines, which is the same as "diff -B" (ignore blank lines) of GNU diff. * ap/diff-ignore-blank-lines: diff: add --ignore-blank-lines option
2013-06-19diff: add --ignore-blank-lines optionLibravatar Antoine Pelisse1-0/+3
The goal of the patch is to introduce the GNU diff -B/--ignore-blank-lines as closely as possible. The short option is not available because it's already used for "break-rewrites". When this option is used, git-diff will not create hunks that simply add or remove empty lines, but will still show empty lines addition/suppression if they are close enough to "valuable" changes. There are two differences between this option and GNU diff -B option: - GNU diff doesn't have "--inter-hunk-context", so this must be handled - The following sequence looks like a bug (context is displayed twice): $ seq 5 >file1 $ cat <<EOF >file2 change 1 2 3 4 5 change EOF $ diff -u -B file1 file2 --- file1 2013-06-08 22:13:04.471517834 +0200 +++ file2 2013-06-08 22:13:23.275517855 +0200 @@ -1,5 +1,7 @@ +change 1 2 + 3 4 5 @@ -3,3 +5,4 @@ 3 4 5 +change So here is a more thorough description of the option: - real changes are interesting - blank lines that are close enough (less than context size) to interesting changes are considered interesting (recursive definition) - "context" lines are used around each hunk of interesting changes - If two hunks are separated by less than "inter-hunk-context", they will be merged into one.

2012-04-26docs: stop using asciidoc no-inline-literalLibravatar Jeff King1-1/+1
In asciidoc 7, backticks like `foo` produced a typographic effect, but did not otherwise affect the syntax. In asciidoc 8, backticks introduce an "inline literal" inside which markup is not interpreted. To keep compatibility with existing documents, asciidoc 8 has a "no-inline-literal" attribute to keep the old behavior. We enabled this so that the documentation could be built on either version. It has been several years now, and asciidoc 7 is no longer in wide use. We can now decide whether or not we want inline literals on their own merits, which are: 1. The source is much easier to read when the literal contains punctuation. You can use `master~1` instead of `master{tilde}1`. 2. They are less error-prone. Because of point (1), we tend to make mistakes and forget the extra layer of quoting. This patch removes the no-inline-literal attribute from the Makefile and converts every use of backticks in the documentation to an inline literal (they must be cleaned up, or the example above would literally show "{tilde}" in the output). Problematic sites were found by grepping for '`.*[{\\]' and examined and fixed manually. The results were then verified by comparing the output of "html2text" on the set of generated html pages. Doing so revealed that in addition to making the source more readable, this patch fixes several formatting bugs: - HTML rendering used the ellipsis character instead of literal "..." in code examples (like "git log A...B") - some code examples used the right-arrow character instead of '->' because they failed to quote - api-config.txt did not quote tilde, and the resulting HTML contained a bogus snippet like: <tt><sub></tt> foo <tt></sub>bar</tt> which caused some parsers to choke and omit whole sections of the page. - git-commit.txt confused ``foo`` (backticks inside a literal) with ``foo'' (matched double-quotes) - mentions of `A U Thor <author@example.com>` used to erroneously auto-generate a mailto footnote for author@example.com - the description of --word-diff=plain incorrectly showed the output as "[-removed-] and {added}", not "{+added+}". - using "prime" notation like: commit `C` and its replacement `C'` confused asciidoc into thinking that everything between the first backtick and the final apostrophe were meant to be inside matched quotes - asciidoc got confused by the escaping of some of our asterisks. In particular, `credential.\*` and `credential.<url>.\*` properly escaped the asterisk in the first case, but literally passed through the backslash in the second case.

2012-03-01diff --stat: add config option to limit graph widthLibravatar Zbigniew Jędrzejewski-Szmek1-7/+9
Config option diff.statGraphWidth=<width> is equivalent to --stat-graph-width=<width>, except that the config option is ignored by format-patch. For the graph-width limiting to be usable, it should happen 'automatically' once configured, hence the config option. Nevertheless, graph width limiting only makes sense when used on a wide terminal, so it should not influence the output of format-patch, which adheres to the 80-column standard.

2012-03-01diff --stat: enable limiting of the graph partLibravatar Zbigniew Jędrzejewski-Szmek1-0/+2
A new option --stat-graph-width=<width> can be used to limit the width of the graph part even is more space is available. Up to <width> columns will be used for the graph. If commits changing a lot of lines are displayed in a wide terminal window (200 or more columns), and the +- graph uses the full width, the output can be hard to comfortably scan with a horizontal movement of human eyes. Messages wrapped to about 80 columns would be interspersed with very long +- lines. It makes sense to limit the width of the graph part to a fixed value (e.g. 70 columns), even if more columns are available.

2012-03-01diff --stat: use a maximum of 5/8 for the filename partLibravatar Zbigniew Jędrzejewski-Szmek1-6/+8
The way that available columns are divided between the filename part and the graph part is modified to use as many columns as necessary for the filenames and the rest for the graph. If there isn't enough columns to print both the filename and the graph, at least 5/8 of available space is devoted to filenames. On a standard 80 column terminal, or if not connected to a terminal and using the default of 80 columns, this gives the same partition as before. The effect of this change is visible in the patch to the test vector in t4052; with a small change with long filename, it stops truncating the name part too short, and also allocates a bit more columns to the graph for larger changes.

* rs/diff-whole-function: diff: add option to show whole functions as context xdiff: factor out get_func_line()
2011-10-10diff: add option to show whole functions as contextLibravatar René Scharfe1-0/+4
Add the option -W/--function-context to git diff. It is similar to the same option of git grep and expands the context of change hunks so that the whole surrounding function is shown. This "natural" context can allow changes to be understood better. Note: GNU patch doesn't like diffs generated with the new option; it seems to expect context lines to be the same before and after changes. git apply doesn't complain. This implementation has the same shortcoming as the one in grep, namely that there is no way to explicitly find the end of a function. That means that a few lines of extra context are shown, right up to the next recognized function begins. It's already useful in its current form, though. The function get_func_line() in xdiff/xemit.c is extended to work forward as well as backward to find post-context as well as pre-context. It returns the position of the first found matching line. The func_line parameter is made optional, as we don't need it for -W. The enhanced function is then used in xdl_emit_diff() to extend the context as needed. If the added context overlaps with the next change, it is merged into the current hunk. Signed-off-by: Rene Scharfe <rene.scharfe@lsrfire.ath.cx> Signed-off-by: Junio C Hamano <gitster@pobox.com>
